'3 Claims.

My invention relates to improvements in spigots for use in drawingliquid from closed drums, tanks, or the like.

The primary object of the invention is to provide an efllcient, simplyconstructed and easily applied, spigot for connection to such drums andwhich is equipped for admitting air into the top of the drumsimultaneously with opening of the spigot and to be automatically lockedopen.

To the accomplishment of the above, and subordinate objects presentlyappearing, a preferred embodiment of my invention has been illustratedin the accompanying drawings, set forth in detail in the succeedingdescription, and defined 1n the claims appended hereto.

In said drawings:

Figure 1 is a view in side elevation, partly broken away, of thepreferred embodiment of my invention applied to a liquid containingdrum,

Figure 2 is a fragmentary view in vertical longitudinal section,

Figure 3 is a fragmentary view in top plan, and

Figure 4 is a view in front elevation, partly in section, of the tubeand valve member.

Referring to the drawings by numerals, I have shown my improved spigotas applied to the usual type of liquid containing drum I having aninternally threaded plug opening 2 in the side thereof adjacent thebottom of the drum and extending through an internal boss 3 provided onthe wall of the drum.

The spigot comprises an elongated, generally tubular barrel 4, ofsuitable material, externally threaded adjacent its rear end, as at 5,to be turned into the opening 2 with its rear end extending inwardlypast said opening for a short distance and provided in front of thethreads, with an external circumferential collar 6 thereon fittingagainst the outer face of the drum I and together with the threadssealing the opening 2. The barrel 4 embodies a depending spout Iimmediately in front of the collar 6 and an extension 8 projectingforwardly from said spout, the extension having a cylindrical axial bore9 in its front end, forming a chamber therein, a reduced axialcounterbore I0 intermediate the bore 9 and spout I and forming a guide,and a pair of laterally spaced ears I I upstanding therefrom in front ofthe bore 9. A radial air inlet duct I2 is provided in the extension 8 infront of the spout I and which extends upwardly into the counterbore I0.An apertured upstanding ear I3 is provided on top of the barrel 4 abovespout I. The purpose of the bores 9, l0,,ears II, and duct I2 and ear I3will presently appear.

An air inlet tube I4 of substantially smaller diameter than that of thebarrel 4 is fitted in the countrbore I0 for endwise sliding movementtherein, said tube extending rearwardly out of said barrel 4 for a shortdistance and having a right angled rear end extension I5 adapted toproject upwardly in the drum I above the normal level of the liquidtherein. The front end of the tube I4 extends through and out of thebore 9 and is formed withan oblique closed tip I6 disposed in the rearof the ears II.

A coil spring I! surrounds the front end of the tube I4 and is housed inthe bore I0 with one end bearing against a resilient washer I8 fittingover said tube and seated against the rear end of said bore, and itsother end bearing against a metal washer I9 sleeve on the tube I I. ,Thelast mentioned end of the spring I1 and the washer I9 are preferablysoldered to the tube I4 as indicated at 20. The described spring IIurges the tube I4 forwardly and the washer I8 forms a seal at the outerend of counterbore I 0.

The rear end of the barrel 6 is closed under forward movement of thetube I 4 through the medium of a disk-like-valve member 2| on said tubeseating against said end of the barrel and backed by a cup washer 22soldered to said tube as indicated at 23. As will be understood, thevalve member 2| by seating against the rear end of barrel 4 establishesthe forward limit of movement of tube I 4.

A bail-like operating hand grip 26 is provided for moving the tuberearwardly to move the valve member 2! into unseated position andthereby open the rear end of the barrel 4 50 that liquid may pass out ofthe same. The hand grip 24 is pivoted at one end to the ears II, as by apin 25, for vertical swinging movement above the barrel 4 forwardly andrearwardly, said pivoted end being provided with an inclined cammingcorner 26 adapted for coaction with the-tip I6 so that under forwardmovement of the hand grip into upright position, said tube is cammedrearwardly in opposition to the spring I! to unseat valve member 2|.Under such rearward movement of tube I4, a port 21 therein is adjustedinto registration with the duct I2 so that atmospheric air is admittedinto the tube H to escape therefrom into the drum and break the vacuumexisting therein above the liquid. As will be manifest, when the handgrip 24 is moved rearwardly, the spring I! will act to move the tube I4forwardly, thereby effecting seating of valve member 2| and adjustmentof port 21 out of regi trat on with. duct l2.

The hand grip 24 is provided with an enlarged free end 20 slotted, as at29, and adapted to swing down against the top of barrel 4 over ear l3,whereby rearward movement of said grip is limited and said grip may belocked against operation by the insertion of a padlock hasp, not shown,through the aperture of said ear. In its rearward limit of movement, thehand grip 24 arches upwardly from the barrel 4.

Means are provided for automatically locking the hand grip in theforward limit of movement thereof and thereby locking the valve member2| in unseated open position. The locking means comprises a rod 30pivoted at one end, as at 3|, to said hand grip 24 to swing downwardlythereon into vertical position under the influence of gravity, when thehand grip is swung into its forward limit of movement, and so that itsfree end is opposed to the top of barrel 4 thereby blocking downwardswinging of said hand grip. When the hand grip 24 is swung rearwardly,the rod 30 may be manipulated by the fingers to fold the same inwardlyof said grip so that it will lie on top of the barrel 4 in the rearwardlimit of movement of said grip.

The valve member 2i and washer 22 are of substantially the same diameteras the inner or rear end of the barrel 4 so that these parts may clearthe opening 2 when the spigot is applied.

A small hole 32 is provided in the extension 8 for the insertion of anail, not shown, laterally into the bore 9 in front of washer l9 whenthe tube I4 is in its rearmost limit of movement, so that said tube maybe held retracted in an out of the way position when assembling the handgrip 24 with the barrel 4 or replacing said grip with a new one.

It may be explained, that spring ll frictionally looking to the washerl8 and being soldered to the tube l4 acts to prevent the tube l4 fromrotating in the barrel 4.

The foregoing will, it is believed,- suflice to impart a clearunderstanding of my invention without further explanation, since theoperation of the same has been set forth in connection with thedescription of parts.

Manifestly the invention, as described, is susceptible of modificationwithout departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of subjoinedclaims.
